It's easy to tell what the system timezone is at any instant, but so  
far as I know there's no reliable way to be notified when it changes.  
So, if the goal  is to keep the alarms up-to-date with the system  
timezone without quitting & restarting (or having a "reset system  
timezone" menu item), Chandler would have to poll the OS.

This is very straightforward.
